Smart belt with electrical stimulation function {SMART BELT HAVING ELECTRICAL STIMULATION}

The present invention relates to a belt, and more particularly, to a smart belt having an electrical stimulation function.

Currently, various types of smart devices are on the market. Most of these smart devices can communicate with each other or detect changes in the surrounding environment with sensors to implement various functions, and are being used in various fields. In particular, life logging (Life Logging) has recently become an issue and is mainly applied to smart watches. These devices measure the user's biometric data such as heart rate, blood sugar, electrocardiogram, oxygen saturation, and exercise amount and location information and manage it in conjunction with a smartphone.

People who sit in one place for a long time or stand for long periods of time have difficulty maintaining a correct back posture. Failure to maintain correct back posture can lead to various diseases such as herniated discs, back pain, and posture distortion. In addition, abdominal obesity due to lack of exercise and dietary changes can also cause health problems. In order to maintain a correct back posture and to prevent and reduce abdominal obesity, it is necessary to maintain constant tension of the abdominal core muscles. However, a conscious contraction effort is required to strengthen the abdominal core muscles. Therefore, it is not usually used well, so it is difficult for people to keep the abdominal core muscles in tension for a long time in daily life. Therefore, there is a need for a smart device that monitors the abdominal core muscles instead.

The present invention is to solve the above technical problem, and an object of the present invention is to strengthen the muscles of the abdomen or correct the posture by sensing the abdominal circumference, abdominal pressure, or the inclination of the posture and applying electrical stimulation. It is to provide a smart belt.

A smart belt according to an embodiment of the present invention includes: a buckle including an electrical stimulation device for detecting the abdominal pressure and posture inclination of a wearing part and applying electrical stimulation; and a contact portion in contact with the buckle, wherein the contact portion is made of a material different from that of the non-contact portion, and includes a band for wrapping the wearing portion, The electrical stimulation device determines the allowable range of abdominal pressure through a mode selector and generates an abdominal warning signal when the abdominal pressure is out of the allowable range, detects the tilt of the posture based on the allowable range, and generates a posture warning signal when the inclination of the posture is out of the allowable range, and the contact portion and the By detecting a material difference between the non-contact parts, an abdominal warning signal may be generated, and electrical stimulation may be applied to the abdominal muscles in response to the abdominal warning signal and the posture warning signal.

According to an embodiment of the present invention, the wearer can periodically observe changes in the abdomen or monitor the posture tilt from time to time by wearing the smart belt. The smart belt according to an embodiment of the present invention can help reduce abdominal obesity of the wearer, prevent diet or low back pain, strengthen abdominal and back muscle strength, and correct posture.

The execution program may be stored and installed in the memory unit 1115 of the user electronic device 1100 through a removable storage medium (eg, USB or memory card) or by downloading from the server 2000 . The execution program may include authentication data for self-authentication of the user electronic device 1100 described with reference to FIG. 9 .

In step S220, the application manager 2320 may determine whether the installation of the execution program is successful. If the installation of the execution program fails (NO), the application manager 2320 may guide the program installation failure (S225). If the buckle program installation is successful (YES), the application manager 2320 may perform step S230.

In step S230 , the application manager 2320 may check whether the communication unit 2100 , the storage unit 2200 , and the control unit 2300 of the server 2000 operate normally. The application manager 2320 may check whether the customer can normally use a user application or a buckle program provided by the server 2000 using the user electronic device 1100 .

In step S231 , the application manager 2320 may check the operation of the communication unit 2100 of the server 2000 . First, the application manager 2320 may check whether the user electronic device 1100 is smoothly connected to the server 2000 through the operation of the communication unit 2100 . The communication unit 2100 may receive user information, etc. from the user electronic device 1100 , and may check whether abdominal information or posture tilt information may be input from the server 2000 .

In step S232 , the application manager 2320 may check the operation of the storage unit 2200 of the server 2000 . The application manager 2320 may check whether the storage unit 2200 normally stores the information received from the communication unit 2100 in the member DB 2210 , the abdomen DB 2220 , and the posture DB 2230 . That is, the user information input from the user electronic device 1100 is stored in the member DB 2210 , the abdominal circumference information or the abdominal pressure information of the user is stored in the abdominal DB 2220 , and the user's information is stored in the posture DB 2230 . You can check whether the posture tilt information is saved.

In step S233 , the application manager 2320 may check the operation of the controller 2300 of the server 2000 . The application manager 2320 may check whether the processor 2310 of the controller 2300 operates normally and the operation of the member information manager 2330 , the abdomen information manager 2340 , and the posture information manager 2350 . The application manager 2320 may check whether the buckle program operates according to the program command.

The above are specific embodiments for carrying out the present invention. In addition to the above-described embodiments, the present invention will also include simple design changes or easily changeable embodiments. In addition, the present invention will include techniques that can be easily modified and implemented using the embodiments. Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be defined by the claims described below as well as the claims and equivalents of the present invention.

Claims (1)

A buckle including an electrical stimulation device for sensing the abdominal pressure and posture tilt of the wearing portion and applying electrical stimulation; and
and a contact portion in contact with the buckle, and the contact portion is made of a material different from that of the non-contact portion, and includes a band for wrapping the wearing portion,
The electrical stimulation device is a smart belt that provides an abdominal warning signal and a posture warning signal to the user through muscle contraction by electrical stimulation when the abdominal pressure is out of the allowable range or when the inclination of the posture is out of the allowable range.
